RHBA-2015:0520 - Bug Fix Advisory

Topic

Updated firewalld packages that fix several bugs and add two enhancements are now available for Red Hat Enterprise Linux 7.

Description

The firewalld packages contain the firewalld service daemon that provides a dynamic customizable firewall with a D-Bus interface.

Bug fixes:

• When the user incorrectly used the iptables command, the firewalld daemon did not return any error message to the command line. With this update, an error message is returned. (BZ#1057095)
• The PK_ACTION_INFO and PK_ACTION_CONFIG PolicyKit domains were not used consistently as certain methods in the firewalld source code required PK_ACTION_INFO whereas certain required PK_ACTION_CONFIG. The code has been modified to use the domains consistently. (BZ#1061809)
• Several changes made in the upstream firewalld manual pages were not propagated to the firewalld manual page that was packaged with the firewalld packages. The packaged manual page has been modified to include all relevant changes. (BZ#1071303)
• The "firewall-cmd --get-target" command returns the target of a permanent zone. The command referred to the default target as "{chain}_{zone}", which was not clear. Now, the command refers to the default target as "default" to avoid possible misunderstandings. (BZ#1075675)
• The at_console="true" condition was used in the firewalld D-Bus policy file. This condition is deprecated. Also, firewalld had difficulty being used on servers where users were logged in using the SSH protocol or the Cockpit server manager. Now, at_console="true" has been removed, and the authorization is performed by the PolicyKit utility instead. (BZ#1097765)
• Due to a missing argument in the lockdown-whitelist.xml file, when a non-root user locked the firewall configuration using the "Options" tab in the firewall-config GUI, only the root user was able to unlock it again. With this update, lockdown-whitelist.xml has been fixed to allow non-root users to unlock the firewall configuration as expected. (BZ#1099065)
• The Lockdown property in the firewalld source code was read-only. As a consequence, an attempt to lock or unlock the firewall configuration using the "firewall-cmd --lockdown-{on,off}" command failed. The underlying source code has been modified, and the user is now able to lock or unlock the firewall configuration as expected. (BZ#1111573)
• The "--permanent --add-interface" option is supposed to be used only for interfaces that are not managed by the NetworkManager utility. This update modifies the firewall-cmd(1) and firewalld.zone(5) manual pages to explain the correct usage of the option. (BZ#1112742)
• Devices that do not have a zone explicitly set use the default zone. If the default zone was changed, the firewall-config GUI did not reflect this change in the "Change Zones of Connections" tab until the GUI was restarted. This update applies a patch to fix this bug, and when the user changes the default zone, the default zone is also changed in "Change Zones of Connections". (BZ#1120212)
• Several ports are supposed to be opened on the Satellite 6 server. The firewalld daemon was not aware of those ports, and therefore the user had to set the ports manually. With this update, the new RH-Satellite-6.xml file has been added to the /usr/lib/firewalld/services/ directory, which ensures that all required ports are set automatically. (BZ#1135634)

Enhancements:

• It is now possible to copy changes made in the runtime configuration to the permanent configuration without manually remaking all the changes also in the permanent environment. (BZ#993650)
• The firewalld D-Bus API provided two different sets of APIs; one for the runtime configuration and one for the permanent configuration. This enhancement unifies the two sets of APIs by implementing the matching runtime methods directly into the permanent environment without the need to use the Python client class. (BZ#1127706)

Users of firewalld are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
